Recommendation
If you must drive, the least risky morning window is 7:00-8:00 AM before the flood watch begins and before storms become likely. For evening travel, conditions remain poor; avoid driving from 6:00 PM through late night, and only consider travel after 11:00 PM if absolutely necessary and roads are not flooding.
